26、hod for determining the consistency of slurry surfacing mixtures. This test is dedicated to Slurry Seals (D 4mm).NOTE 1 The method can be used as a mix design aid to determine the amount of water required to form a stable, workable mixture.NOTE 2 To obtain the correct consistency, it can be necessar
27、y to repeat the test with different known percentages of water.This European Standard applies to slurry surfacing for roads, airfields and other trafficked areas.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for
28、its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.EN 10975, Tests for mechanical and physical properties of aggregates Part 5: Determination of the water content by drying in
29、 a ventilated oven3 Apparatus1) Mould, made from sheet metal or hard plastic, in the form of a frustum of a cone (see Figure 1), of height (75 1) mm, inside diameter at the top of (40 1) mm, and an inside diameter at the bottom of (90 1) mm.Dimensions in millimetresFigure 1 Mould2) Measured metallic
30、 template, 250 mm 250 mm, marked with an indelible flow scale of eight concentric circles, as shown in Figure 2, each increasing in radius by 10 mm. The inner circle shall 5BS EN 122743:2018EN 122743:2018 (E)have a diameter of 90 mm. The circles may be scribed with a compass but the lines shall not
31、be thicker than 0,5 mm. All dimensions shall be to a limit deviation of 1 mm. On the plate sheets of nonabsorbent transparent paper are used to spread the slurry mix and to determine the slurry flow.Figure 2 Flow scale3) Balance having a suitable range capable of weighting a sample to the nearest 0,
32、1 g.4) Beaker or container of at least 0,5 L capacity.5) Stirring rod.6) Oven, capable of accommodating the sample and maintaining a temperature of (110 5) C.4 Procedure1) Wet aggregates may be used, preferably at their own natural moisture or dry. In case of natural moisture, determine the water co
33、ntent W by drying in an oven at a temperature of (110 5) C until constant mass is achieved, according to EN 10975.2) To homogenize the bitumen emulsion, stir it manually.3) The test temperature shall be at ambient temperature, (23 5) C.4) Weigh a sample of (400 5) g of dry aggregate or (400 x (100+W
34、)/100 5) g of wet aggregates (where W is the water content of aggregates) and place it in the beaker or container. Weigh and add any reactive filler needed in the mixture (e.g. cement or hydrated lime). Add any predetermined quantities of additives and prewetting water and record the amount of compo
35、nents in grams (accuracy: 1 g).5) Add the selected amount of bitumen emulsion to the other mixture components in the beaker and use the stirring rod to mix until the mix is homogeneous.6) Place the non-absorbent paper flow sheet on a level table. Place the mould with its base centred on the flow she
36、et. Fill the mould with the slurry mixture, strike the top surface level with the top of the cone using a spatula and immediately lift the mould clear of the mixture with a smooth vertical motion.6 BS EN 122743:2018EN 122743:2018 (E)7) Allow the slurry mixture previously supported by the mould to fl
37、ow and record the measurements after (10 2) s.5 Expression of resultsThe outflow of the slurry is measured at four points 90 apart from the circle “0”, averaged and recorded as slurry flow, in mm; pre-wetting water, in % by mass; bitumen emulsion in the mix, in % by mass.6 Test reportThe test report
38、 shall include:a) reference to this European Standard;b) any deviation from the procedure described in the standard;c) reference of the sample;d) date of test;e) test temperature at which the test has been performed;f) name of person conducting test;g) results as stated in Clause 5 Expression of Res
39、ults;h) remarks.7 PrecisionThe statistical parameters for the repeatability and reproducibility for this test are unknown.7BS EN 122743:2018This page deliberately left blankBSI is the national body responsible for preparing British Standards and other standards-related publications, information and
